Abstract: A bevelling machine for printed circuit boards having a board transport assembly (45) for passing a board between two grinding wheels (11) each mounted independently on a slide (7, 8) moved by an actuator (13) so that the wheels (11) overlap along the path of travel of a board to bevel two edges thereof at the same time. The position of at least one side of a board relative to the centre line of travel is sensed and the slide (7,8) mounting the grinding wheel which produces a bevel on the sensed side is moved to a position determined by the position of the sensing means so that the depth of cut on each side of the board is substantially the same for different thicknesses of board.
